Flora of North America species comparison

many, erect, unbranched or branched, sometimes with small, leafy axillary branches, hairs spreading, long, soft, mixed with shorter stipitate-glandular ones.

solitary or few, erect to ascending, unbranched, rarely branched, hairs spreading, long, soft, eglandular, others shorter and glandular.

green or purple-tinged, lanceolate to linear-oblong, 0.8–6.1 cm, not fleshy, margins wavy, involute, 0(–3)-lobed, apex rounded to acute;

lobes spreading-ascending, narrowly lanceolate, apex acute to acuminate.

green to sometimes brownish, rosette leaves persisting or withered at anthesis, oblanceolate to oblong-lanceolate, 1–3 cm, usually 0-lobed;

cauline leaves linear-lanceolate to oblong-lanceolate, 2–7(–8) cm, not fleshy, margins plane, sometimes wavy, involute, 3–7(–9)-lobed, apex acute to acuminate;

cauline leaves: lobes spreading to ascending, linear to oblong, (2–)5–25 mm, apex acuminate.

3–34 × 1.5–3.5 cm;

flowers usually distichous, remote, except distalmost;

bracts proximally greenish, distally greenish, reddish, orange-red, or dull orange, rarely yellow, proximal bracts frequently greenish throughout, lanceolate to narrowly ovate or narrowly oblong-elliptic, 0(–3)-lobed, proximal wavy-margined;

lobes ascending, triangular, short, arising near apex, apex acute to obtuse.

2–35 (longest in fruit) × 1.5–6 cm;

bracts proximally greenish to brownish green, distally red, sometimes orange, yellow, or white, lanceolate to obovate, 3(–5)-lobed;

lobes spreading-ascending, lanceolate and longer on proximal bracts, becoming oblanceolate, shorter, and wider on distal bracts, arising from distal 3/4 of blade, apex acute to rounded.

tube 14–18 mm;

beak and often abaxial lip exserted;

beak adaxially dull orange or dull red, rarely yellow, 14–19 mm;

lobes linear-lanceolate, apex acute.

colored as bracts, 17–23(–28) mm;
